Chemical castration
Traditionally, surgical castration of dogs has been seen as a standard way to prevent unwanted mating and to reduce the risk of medical conditions such as testicular cancer and prostate disease. Recent research shows that around 25% of pet owners have a degree of concern regarding surgically castrating their pet.

What is chemical castration?
Chemical castration is an alternative to surgical neutering in male dogs using Suprelorin implants. Suprelorin® releases a continuous low dose of the hormone deslorelin acetate. The implantation procedure is similar to that of inserting a microchip and can usually be carried out in a routine consultation.
How does it work?
The deslorelin in Suprelorin® implants mimics the naturally occurring hormone GnRH which controls the secretion of other hormones involved in fertility. After deslorelin is implanted under the skin, testosterone production by the testes is inhibited. This means that your pet becomes infertile with a reduced libido.
How long does it last?
The full effects of chemical castration can be seen at about six weeks in dogs. There are 2 sizes of implant available, lasting either 6 or 12 month in dogs, after which the dog can be re-implanted if necessary.
When is chemical castration useful?
It is used in healthy, sexually mature dogs that have not been neutered to make them temporarily infertile. Circumstances when this may be useful include :-
- Where breeding may be planned at a later date
- To see the effects of castration on behaviour without the permanence of surgery (in some dogs anxiety related disorders can be worsened by castration)
- Where we wish to avoid the risks associated with surgical castration (due to the general anaesthetic required), for example in elderly dogs or those with other health problems
Use in other species
Sureplorin is also licensed for use in male cats and ferrets.
